The PC (Personal Computer) is a highly configurable and upgradable gaming platform that, among home systems, sports the widest variety of control methods, largest library of games, and cutting edge graphics and sound capabilities.

@JTB123: The Gigabyte brand 660 Ti has slightly better benchmarks and is a much quieter GPU than the EVGA card. It also has the lowest temparatures.

Further, I have pretty close to that exact build, except I have one 1TB HDD and a 120GB SSD instead. I use this power supply. Whatever power supply you choose, try to go for one that's at least semi-modular so you don't have an octopus of wires eating your airflow.

850's actually more than you'll need with that rig, even if you add another video card and another ssd or hdd. I'm running SLI and more hardware and peripherals in my case than you've got with a Corsair HX 750. I wish I had one of those readers so I could see how many watts I'm actually using, but I imagine I'm somewhere around 500 or so?

I'm on my phone at the moment but I would recommend getting 650 watt Ultra brand supply from tiger direct I only say this because of experience no issues and has a lifetime warranty. 650 watts is sufficient for your current setup .

@believer258: I had thought about adding a second graphics 660 a little later so that is something I want to consider regarding my PSU. Or at that point would it just be better to go with a single, more powerful card?

Also, what is the main benefit of a semi/modular PSU? I remember the Tested guys mentioning that in Jeffs build.

For me, personally, I've heard that there are some problems with Crossfire and SLI with some games, particularly with microstutter, so I wouldn't do anything like that for a while. I would just go for a 680 if you're looking for that kind of power.

BUT

People have done it and it's a successful technology, so if you're comfortable with disabling one card for some games then you should be fine. But I don't have a ton of experience with this technology, so in this case Google is your friend.

@Toxeia: 660 ti's peak at like 150 watts, your cpu probably dont use more than that either, couple of watts here and there for mobo and hdd's and you are close to that 500 you were talking about, but this is a peak value.

@JTB123: the benefit is that you can detach all the cables you dont have any use for.

@Devildoll: 670's but yep. I actually ordered a thing to read power usage today so I'll find out exactly.

@JTB123: If your case is even half decent it should have paths for wiring so it doesn't fill your case. Mine all routes behind the motherboard's panel so the only wires that are visible are going to the video card or my internal USB expansion card. Modular PSUs really help with this though if your case doesn't have that.

This will be my first build so if having a modular PSU will make things a little easier then that's great, even if it is just less cables to work around. I swapped out RAM seeing as the price difference between 1600 and 1866 was only £8, and went with the 850 PSU just in case I need it further down the road. Added in the faster RAM and PSU the final build is below:
